I honestly don't understand why people are putting up with this shit. A company who deliberately rooted PCs with a trojan on store-bought CDs, removed features from a game machine after it was already purchased and used, exposing customer information in plain text in an internet-facing database, and people still give them money?? My mind is boggled.
XBone? Nope, not with that built-in NSA camera and microphone.
Nintendo? Isn't theirs a handheld with a dinky screen?
PCs? When you can no longer actually own a game?
These kids would love Quake II. None of the bullshit you put up with today. Computer gaming used to be fun rather than a way to be stolen from by rich assholes.
I wonder if Road Rash 95 will run on Windows 7? AFK
It's not just the NSA. I'm outraged that they're spying on citizens, even though they have no reason to be interested in me. I'm outraged that advertisers insist on knowing my GPS position, who's on my contacts list, etc. It's creepy and it pisses me off. I thought stalking was illegal?
All the KSHE app wanted was access to the internet, sound chip, and sleep circuitry (so It wouldn't stop playing when the screen blanked out). So far, playing KSHE is the only thing the Android does that the Motorola feature phone wouldn't, although the camera is a lot better and it has way more storage. Hell, I could play pac-man on the feature phone without telling them who I knew and where I was.
Wait - OK, this one is "waterproof". Dropping it in the toilet isn't as dangerous (that's how my Razr died ten years ago).
The solution you are looking for is SElinux, and it is already enabled in the latest cyanogenmod nightlies.
I'd love to do that but my carrier wouldn't go along. Hell, it's the latest Android and they disabled sideloading apps before shipping it. If I installed Linux it would be a four inch wifi tablet.
This isn't going to make you stop aging at 30, it will simply slow the aging process. Have you not noticed that some people at 50 look 70 and some 60 look 50? Some people simply age faster than others and this study shows why.
And as this study shows, genetics can play an even larger part. But try convincing my 84 year old mother that, she's convinced eating right and getting exercise was why she's old and healthy, despite the fact that she's the baby of the family and almost all of her siblings are still alive. One is 99 and owned a bar when she was middle aged, my guess from knowing bar owners she was far from a teetotaler.
Now I understand what part of my DNA had the health screeners say my vitals showed a healthy forty year old and excellent for someone 61. They thought I must work out, but I get little exercise and eat a lot of junk food, drink a little beer and have smoked pot for four decades. Most people are amazed that I'm over 50. Of course, my rDNA won't keep me from staggering in front of a bus or something.
If all your grandparents died of natural causes before age 60, no amount of diet or exercise will keep you alive past 70. But perhaps this research will come up with something that will.
I just upgraded to a smart phone and hated how every app I wanted to download wanted everything. Why should Pac Man need my contacts list and GPS information? So when I saw the submission I though ALL RIGHT!!!
Sadly, this is interesting but solves a completely different problem, so I guess I'll be appless for a while (except the KSHE app, everything it needed had to do with its workings).
TFA doesn't say if this could be used for private messages between individuals. But we need to have every damned thing encrypted, the NSA is only one entity that knows everything about your online life. I think it's damned creepy either way and would like to see it outlawed. Fat chance, though, since the corporate spies own the government.
Cylinders didn't last because platters were superior in every way. Cassettes died for the same reason -- CDs are superior, especially after burners came on the market.
I'd like to see some studies. An electronically generated sawtooth wave doesn't get that shape by harmonics, although normal sounds do. I don't think the ear discerns the difference between waveforms from discerning harmonics any more than a dog understands the math behind catching a ball. What you say is logical, but I'd like to see the assumption demonstrated using test subjects. Sometimes with math you may get the right answer but missing some variables.
I have read up on it, Nyquist doesn't stop aliasing, it prevents any tone higher than half the sample rate from recording at all, what comes out is a very audible screech unless frequencies above Nyquist are filtered out. Nyquist explains this mathematically. You can graph it out on paper, the math isn't hard.
Nope, I tried to find a citation but wikipedia doesn't say how they worked, but one of my undergrad physics classes was about sound, which included how they got four channels out of a single groove. Until that class I had assumed what you assert, but I was wrong. The up and down movements were the mono channel (both channels) and the side to side was a single channel, which was mixed with the mono channel to derive the other channel.
With quadrophonic records the rear channels were modulated with a 44kHz tone and demodulated during playback. Like CDs, these records were limited to a 20kHz ceiling and the difference was obvious; the quad records missed something, the same something CDs lack.
The "loudness war" is an indication of why it really doesn't make any difference, if everything were still analog today's engineers would be making pretty much the same mistakes.
As to having the equipment to play a 15kHz tone, tweeters are cheap, it's the woofers that cost. That's what killed quadrophonic stereo, the cost of speakers (and to a lesser extent electronics). We have surround sound now because they don't use woofers any more; a "woofer" today was simply a large squawker back in the '70s.
Import taxes were the highest cost. I had a pair of speakers with five drivers per enclosure, a 15 inch woofer, two squawkers 6 and 4 inches, a tweeter and a "super tweeter" with a range of 15kHz to 30kHz. They had a response from 10 Hz to 30kHz and a flat response from 20Hz to 22kHz. I got them in Thailand when in the Air Force, the suckers were well over $500 each here but I only paid $200 for the pair. Best sounding speakers I ever heard.
Today those speakers would be worth less because they had a range that modern music doesn't use. Today's engineers would limit response to 300Hz to 20kHz (or less) with the stupid limitations on dynamic range they would needlessly use.
If the sampling rate were higher digital would blow any analog out of the water, but today's engineers don't even try to make a recording of an acoustic guitar sound like a real guitar. Nobody cares about fidelity any more.
That was his original user name but his karma is so far in the toilet that an AC who starts at 0 has a better chance of being seen. He puts it there and is laughing at you right now for getting his troll seen. You might want to look at this.
The platter was introduced in 1894, and a turntable you can buy today will play a record made for it. However, as for longevity, I agree that properly archived and backed up digital media can last forever, I was correcting his statement that with analog you had to change formats every generation. You didn't.
I wonder how long that analog record on Voyager will still be readable, though?
That's sad, the library here is excellent and has a wide ranging interlibrary program, there are few books you can't get. I'd hate to be stuck in your town.
There aren't any free libraries - even if you're not paying for them in any way, somebody is.
The money comes from your taxes, so they're free like freeways are free. The one here is excellent, no way will I ever rent books. You're paying for that library anyway, use it.
Your "Edison" flat disks weren't made by Edison, he used wax cylinders, the gramophone was in existence in 1894 and a turntable you can buy today will play one -- the formats were all backwards compatible; a monophonic record player from 1950 would play a quadrophonic LP with all four channels coming from its speaker.
Until the '40s all records were recorded in one take straight to shellack or vinyl; tape wasn't yet good enough, and wire recorders were not useful at all for music. The grooved platter medium lasted for over a hundred years and hundred year old records are still playable on new turntables.
Likewise, monophonic tapes would play on stereophonic and quadraphonic decks.
I'd have no idea where to get an 8-track player today even though it's an analog format.
You don't need a cartridge player, you can respool the tape and play it on a reel to reel. But 8-track tapes sounded like shit and cut songs off in the middle. I never owned one and never could figure out why they caught on, I'd already been using cassettes to record my albums for the car.
I believe they do, quadrophonic records never sounded as good as their stereo counterparts on stereo equipment.
The way they did quadraphonic was to modulate the rear channels with a 40kHz tone and filter out all sound information above 20kHz as with modern CDs. They had the same unnatural sound. All channels were in the audible portion, which was mixed with the rear channels to remove them from the front channels on quadrophonic playback.
I've heard albums through good equipment that if you closed your eyes the band was in the room with you. I've never heard a CD I would mistake for a live performance.
Digital has no problem with low frequencies. High frequencies are what it has trouble with. Digital is better than analog at low frequencies. Your booming pipe organ will have no problem with digital, but the violins and flutes may.
Sample rate: a higher sample rate allows for higher frequency representation. As in, if you have a sample rate of 48,000Hz, you can play back a frequency of 24,000Hz (already above the range of human perception). Higher sample rate = more high frequencies you can't hear.
The higher the frequency the more aliasing distortion you have. A fifteen kHz tone has only three samples per crest making a sine wave indistinguishable from a sawtooth wave. Tripling or quadrupling the sampling rate would greatly reduce aliasing.
Considering that he's an engineer with decades of experience, that seems unlikely. You remind me of a 19 year old classmate in college who questioned the professor's knowledge of the subject, who told the kid "Son, I've forgotten more than you ever learned."
He's obviously done the math. Can you tell a 15kHz sine wave from a 15kHz sawtooth wave? A CD can't, because there are only three samples per crest and almost every teenager can easily hear 15kHz.
I do fault more modern engineers, though. Why does the Led Zeppelin "Presence" LP have more dynamics than the CD does? CDs have a greater dynamic range so someone must have screwed up the remix. Yes, I was disappointed when my brand new CD didn't sound as good as the old LP of the same album. Boston's was so bad the musicians complained. Zappa refused to release a digital version of their Fillmore East album until his deathbed because the quality wasn't good enough for him.
